platelet activating factor

The content of PAF is very low in the body, the active concentration is 10-7～10-9mol/L, its half-life is 30s, it is not easy to capture; its structure is close to that of phospholipid, it is difficult to separate and purify; it has many molecular genus itself, and its biological activity has Very different. In recent years, scholars at home and abroad have done a lot of work. In summary, there are three main types of methods for PAF detection: 1 biological detection method; 2 physical and chemical method; 3 immunological method. This section focuses on biological testing methods. Basic Information Specialist classification: examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: No relevant information. Normal value: PAF (biological assay): 16.90-100.34 μg / L Above normal: Found in children with bronchial asthma, cerebral infarction, myocardial infarction. negative: Positive: Reminder: Up to now, there is no recognized and standard method for quantitative detection of PAF. Normal value Biological assay 16.90 ~ 100.34μg / L. Clinical significance Increased in children with bronchial asthma, cerebral infarction, myocardial infarction. High results may be diseases: Pediatric heparin-thrombocytopenia-thrombosis syndrome, bronchial asthma in children Until now, there is no recognized and standard method for quantitative detection of PAF. The future research direction of PAF detection is to establish an ideal alternative method to be extended to clinical applications. Inspection process Same as bioassay. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Generally not.
